A host becomes available but it takes still more time to make it workable because you need to boot everything. +iv) cold starts use zero power or very minimal --> idle power of a node that is turned off. Inactive have minimal power draw, but the downsides is that nodes may not be available immediately. +Inactive takes more time to boot e.g., 5 minutes. +The more you can predict how many nodes you will need to more you can save power without impacting the performance. + +The bachelor focus -- the primary focus should be on the design of the digital twin. +Be careful that you do not make implementing the main topic of the bachelor thesis. +The main topic should still be digital twinning. + +The digital twin is activated in 2 ways: either the operators prompt the digital twin when they run a workload or the digital twin sends a notification to the datacenter. + +IBM Dublin := you have metrics being managed and policies can decide to do actions. +And these actions can be many different things. +Currently does not matter what it would -- this could be auto-scaling, scheduling, routing. +What is the difference between routing and scheduling? + +Great success == we do not include AI inference in the bachelor thesis! +Policy decisions can be made using different heuristics --> AI inference. +Do not work too much on the policies. + +The focus of the thesis is the digital twinning part. + +Autoscaling vs. failures vs. scheduling. +MVP soon. + +Why can't we port a digital twin from other domains? +Show that a digital twin can react. + +Show the readers what would the perfect experiment look like in the perfect. + +What a digital twin is --> give the answer in the background somehow. +What do you think a digital twin is? Make it clear. +Why is a specific datacenter digital twin different from what there already is. + +Versen Thesis Awards they are promoted at ICTO today and tomorrow. + |
